The Lowdown

G’day, Rusty here. The next 16 days start a bit slow for Jaconé, but there’s a couple of really solid windows coming up that’ll get the stoke going. The water temp is sitting at 72°, which is pretty much average for this time of year, so nothing unusual there.

Things kick off Tuesday the 18th with a bit of early action. The morning session is clean with a light offshore breeze from the NE, and the swell is 5ft out of the ENE with a short period of 7 seconds. The combined wave energy is moderate (372). It’s a fun, surfable size, but the short period means the waves won’t have much push. It’s best for intermediate surfers, and the crowds can show up sometimes. The afternoon drops off quickly to 3ft with cross-off wind, so the morning is the go.

Wednesday the 19th and Thursday the 20th are pretty ordinary. Swell drops right down to 2ft, and the wind is mostly cross-off or onshore. Not worth paddling out for.

Now, Friday the 21st morning is a standout. The swell jumps to 7ft from the ENE, period stretching to 8 seconds, and the wind is light offshore from the NNE. The combined wave energy is strong (619). This is the best of the first week – clean, solid waves and a proper offshore breeze. It’s getting up there in size, so it’s better for experienced surfers. The afternoon goes to rubbish with a strong onshore, so get out early.

Saturday the 22nd is a write-off with onshore winds and messy swell.

Sunday the 23rd morning is a nice surprise. Glassy conditions, a light offshore from the SE, and the swell is 5ft out of the SSW with a period of 9 seconds. The energy is moderate (391). It’s clean, it’s fun, and the glassy surface makes it a real treat. The afternoon gets a bit bumpy, so make the most of the morning.

Monday the 24th morning is another good one. The swell is 5ft from the SSW, period now up to 11 seconds, and the wind is light offshore from the SE. The energy is getting strong (649). That longer period means the waves have more shape and power, but because it’s a beach break, the long period can make it a bit straight. Still, it’s very clean and worth a look.

Tuesday the 25th is a big one. The swell pushes to 8ft from the S with a 12-second period, and the wind is cross-off from the E. The combined energy is very strong (1850). This is big, powerful, and only for experienced surfers. The conditions are clean, but the size and long period mean it’ll be a handful, especially on a beach break. It’s a standout for the brave.

Wednesday the 26th morning has a good offshore wind from the NE, 30 km/h, with 5ft swell from the SSW and a long 12-second period. The energy is moderate (602). The wind is fresh, but offshore, so it’ll be clean. The size is manageable, but the long period gives it some punch.

After that, from Thursday the 27th through to the end of the period, the surf drops off and the conditions get mixed. There are a few small, clean mornings, but nothing to get excited about. The 1st of September brings a new swell pulse, but the wind is cross-on and choppy, so it’s not worth chasing.

The standout days are definitely Friday the 21st morning for the clean, solid ENE swell, and Tuesday the 25th for the big, powerful south swell. If you’re not up for the big stuff, Sunday the 23rd and Monday the 24th mornings offer clean, fun waves.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
